Abstract
A front landing gear system for an aircraft including a swing arm rotatively coupled to a wheel, a forward link arm rotatively coupled to the swing arm, a oleopneumatic cylinder rotatively coupled to the swing arm, second extension arm and a bulkhead, a plate rotatively coupled to the bulkhead, an actuation device rotatively coupled to the bulkhead and to the plate, where refraction of the linear actuation device causes the plate and extension arms to move upward towards the bulkhead.
Claims19
A front landing gear system for an aircraft including:
- a swing arm rotatively coupled to a wheel;
- a forward link arm rotatively coupled to the swing arm;
- a oleopneumatic cylinder rotatively coupled to the swing arm, second extension arm and a bulkhead;
- a plate rotatively coupled to the bulkhead;
- an actuation device rotatively coupled to the bulkhead and to the plate,
- wherein retraction of the linear actuation device causes the plate and extension arms to move upward towards the bulkhead.
3 more elements
A method of retracting a front landing gear for an aircraft including:
- rotating a base plate towards a bulkhead by actuating an actuator rotatively coupled to the bulkhead and the base plate;
- rotating a piston coupled to the base plate and rotatively coupled to the bulkhead towards the bulkhead as the actuator retracts;
- rotating a wheel coupled to the piston by a first extension arm and second extension arm towards the plate thereby moving the wheel into the position it would occupy if the oleopneumatic cylinder were compressed.
